Which symptom is associated with Kawasaki disease?

Kawasaki disease is primarily known for its acute febrile illness that predominantly affects children. One of the hallmark symptoms of Kawasaki disease is the presence of a prolonged fever, which is often accompanied by specific mucosal changes, particularly "strawberry tongue." This term refers to the characteristic appearance of the tongue, which becomes red and bumpy due to swollen papillae. The fever can last for more than five days and is usually not responsive to typical over-the-counter antipyretics, which distinguishes it from other febrile illnesses.

While sore throat, joint pain and swelling, and headache with fatigue can be symptoms of various other conditions, they are not specific to Kawasaki disease. The combination of prolonged fever and strawberry tongue is critical in making the diagnosis of Kawasaki disease, as it indicates systemic inflammation and the potential for serious complications like coronary artery involvement if not treated promptly. Understanding this correlation helps in recognizing and managing Kawasaki disease effectively in clinical practice.
